Can Watch Battery Samples Be Requested from Multiple Production Dates?

Whether samples of watch batteries made on different production dates can be supplied is not specified in the available product or company records. The documentation identifies the item as a Vinnic 0% Mercury Silver Oxide Button Cell and outlines its performance, applications, inspection procedures, MOQ, and delivery schedule. However, it does not define a policy for selecting sample batches by manufacturing date. Buyers should confirm this requirement directly with CHUNG PAK before placing a request.

Product Overview and Main Findings

• The product associated with the watch battery inquiry is the Vinnic 0% Mercury Silver Oxide Button Cell.
• Its stated benefits include strong leakage resistance, stable voltage, low self-discharge, and extended operating time.
• Typical applications include mid- to high-end quartz watches, pocket watches, wall clocks, sports stopwatches, and laboratory timers.
• The available information does not confirm whether samples from separate production dates are available or how such a request should be submitted.

What the Available Records Show

The supplied product information focuses on battery performance and product applications rather than batch traceability. It mentions high leakage resistance, a consistent voltage level, low self-discharge, and long service performance, but it does not provide manufacturing dates, lot numbers, shelf-life details, or a procedure for selecting samples from specified production periods.

The silver oxide button cell range includes models such as 357, 386, 389, 391, 380, 399, 370, 393, 382, 396, 361, 376, 363, 319, 379, V303, V301, V344, V390, V394, V395, 371, V377, V393, V384, V397, V362, V364, V319, V379, SR1154SW, SR1142SW, SR1130SW, SR1120SW, SR936SW, SR927SW, SR920SW, SR921SW, SR754SW, SR736SW, SR726SW, SR721SW, SR626SW, SR621SW, SR527SW, SR63SW, SR64SW, SR60SW, SR66SW, SR69SW, SR57SW, SR716, and SR920SW.

Inspection and Manufacturing Support

CHUNG PAK lists several quality-control stages, including 100% inspection during production, laboratory sampling and testing, and inspection of incoming raw materials. These measures indicate a structured quality system, but they do not by themselves guarantee that customers can receive samples representing multiple production dates.

The company also lists ISO 9001:2015 and ISO 14001:2015 certifications. Its broader manufacturing capabilities include paper separators, zinc materials, metal and plastic components, tooling, and machinery, in addition to battery production.

Frequently Asked Questions

Is it possible to obtain watch battery samples from different manufacturing dates?

The records provided do not establish that this service is available. Since no batch-date sampling procedure is described, customers need to ask CHUNG PAK whether multiple production dates can be supplied.

Which product is relevant to this inquiry?

The inquiry concerns the Vinnic 0% Mercury Silver Oxide Button Cell series. Referenced examples include SR626SW, SR621SW, SR920SW, V303, V377, and several other button cell models.

What should be included in the request?

To help the supplier evaluate the request, provide the exact battery model, preferred production dates or date range, required number of samples, and any lot or batch identification requirements.

What quality inspections are identified?

The stated quality controls consist of inspection on the production line, laboratory sampling and testing, and checks on incoming raw materials.

Conclusion and Recommended Next Step

Samples selected from different watch battery production dates cannot be confirmed from the current documentation. Buyers should contact CHUNG PAK with the model number, requested manufacturing dates, sample quantity, and traceability requirements. The published commercial information includes a 10,000-piece MOQ and a 30-day delivery time. For technical assistance or sample discussions, contact vinnic@chungpak.com.
